While we all know that FFVII Remake has been delayed from March 3 to April 10 but I believed that most of us may never heard that English version of Persona 5 Royal have two release dates: First in February 20 in some Asian countries and March 31 in western(North America and Europe). No reasons given for such peculiar release dates but most of us can think that Atlus try to avoid FFVIIR and give fans more time to save their money. Unfortunately for Atlus, Square-Enix decided to delay its game for another month and this time FFVIIR will be released later rather than sooner than P5:R and which means Atlus will lose lots of money in west if gamers decided to buy FFVIIR first.
Let's use (vanilla)Persona 5 vs FFXV as a comparison. Back in 2016, Atlus announced that P5 will be released in February 14 2017 but with FFXV aiming for November 29 2016, Atlus delay it to late March in the same year(2017) which gave gamers at least 4 months gap, more than enough for them to save their money if they already bought FFXV. This time though there's only 9 days gap between FFVIIR and P5R and most gamers probably wants to buy FFVIIR first, leaving P5R on the shelf collecting some dust for months.
Perhaps Atlus never aiming for launch sales anyway. Unlike movies, video game industry is more flexible. If you don't buy them at launch day, you can check them months or even years later. This has been proven in December last year(2019), the vanilla P5 sold more than 3 million worldwide despite the Royal version already hit Japanese shelves in October in same year. As I can tell most of them are bought at discounted price especially in Black Friday and Holiday seasons. Most people who bought it are probably tired of FPSes and action RPGs that come out almost every month as well as those who just want some sort of distractions while waiting for other games of different genres to come out later.
As everyone can tell despite both may sold as JRPGs but they are still in different genres. FFVIIR is obviously an action RPG even though it will have turn-based mode which nothing like its 1997 classic and instead it will play like action RPG with much, much slower paced and designed to bore you down so you can switch back to its action mode again. P5R is a pure turn-based JRPG designed to fix some of the flaws of the vanilla version and also adding a new party member who turns out to be a girl. This disappointed lots of female fans who expected a male one instead but given the game's core Japanese audiences are men in their 20s, it shouldn't be a surprise.
While it safe to say that P5R still can do well despite its rivalry with FFVIIR and other JRPGs like Dragon Quest and Trails of Cold Steel, it still be an underdog to much more popular games out there.
